4 - ATR121/141 - Manuale d’usoIntroduction
Thank you for choosing a Pixsys controller.
Versions with three/four digits display are available and the
device fits a wide range of applications with the most diverse
sensors like temperature/humidity/pressure sensors or linear
potentiometers.
Output options include both relay and SSR logic, but it is
possible to configure the unit also as indicator for installations
that do not require control or alarm ouputs.
PID and Autotune allow to adapt the regulation algorithm to
the installation , while LATCH ON function speeds up the device
calibration when linear potentiometers are used.
As on the latest Pixsys instrumentation, the configuration is
further simplified by the Memory cards which are provided with
internal battery and therefore do not require cabling to power
the controller.

14 - ATR121/141 - User manual9 Tuning
Tuning procedure allows to calculate PID parameters to obtain
a good regulation. It means a stable control of temperature/
process on setpoint without fluctuations and fast response to
deviations from setpoint caused by external noises.
Tuning procedure includes calculation and setting of the
following parameters:
• Proportional band (system inertia in °C if temperature).
• Integral time (system inertia expressed in time).
• Derivative time (defines the intensity of the controller
reaction to the variation of the measured value, normally ¼
of integral time).
During Tuning procedure, it is not possible to change the
setpoint.
9.1 Auto-tune
Tuning procedure calculates the controller parameters and can
be manual or automatic according to selection on par. 27 tun
| tune.
9.2 Manual tuning
Manual procedure allows the user greater flexibility to decide
when to update PID algorithm parameters. It can be enabled
selecting Man on par. 27 tun | tune.
•Tuning launch:
Press FNC , display shows t.of, pressing it visualizes process
value and tun | tune (alternately) up to procedure completion
(it can take some minutes). To cancel procedure press FNC and
after to select t.of.
User manual - ATR121/141 - 159.3 Automatic tuning
Automatic tuning activates whenever the controller is switched
on or when the setpoint is modified to a value over 35%. It can
be enabled selecting aut | auto on par. 27 tun | tune.
To exit Tuning and keep P.I.D. values unchanged, press FNC then
to select t.of.
9.4 Memory card (optional)
Parameters and setpoint values can be duplicated from one
controller to another using the Memory card.
2 modes are available:
• With the controller connected to the power supply:
Insert the memory card when the controller is off. At starting
display shows (only if the correct values are saved in the
memory card). Pressing display shows m-Ld. Confirming
with FNC , the controller loads the new data and starts again.
Pressing display shows m-no and the controller starts
keeping values unchanged.

NB: it is not possible to transfer parameters to a device with
different code: red LED is ON.
Updating Memory Card
Insert memory card when controller is on, to copy
parameters. Enter configuration and change at least one
parameter. Exit configuration. Changes are saved automatically.
9.5 Latch On function
For use with input po1 (potentiometer ≤ 6K) and po2
(potentiometer ≤150K ) and with linear inputs (0..10Volt,
0/4..20mA), it is possible to associate start value of the scale
(par. Lo. n.) to the minimum position of the sensor and value
of the scale end (par. Hi. n.) to the maximum position of the
sensor.
It is also possible to fix the point in which the controller will
display 0 (however keeping the scale range between Lo. n. and
Hi. n. ) using the “virtual zero” option by setting u.0m or u.0s on
par. 8 Lat | Latc.
If u.0s is selected, lthe virtual zero will reset after each
activation of the device; with u.0m, the virtual zero remains fixed
once tuned. To use the LATCH ON function configure according
to required operation the par. 8 Lat | Latc1.
For the calibration procedure refer to the following table:

18 - ATR121/141 - User manual9.6 Dual action Heating-Cooling
The ATR121/141 is suitable also for systems requiring a
combined heating-cooling action. Command output must be
configured as Heating PID (par.11 reG. = Hea | Heat and par. 15
p.b. greater than 0), and one of the alarm must be configured as
cooling action (par. 19 AL. = coo | cooL. Command output must
be connected to the actuator responsible for heating action
while the alarm output will control cooling action.
• Parameters to configure for the Heating PID are:
reG. = Hea | Heat Command output type (Heating)
p.b.: Heating proportional band
t.i. : Integral time of heating and cooling
t.d.: Derivative time of heating and cooling
t.c.: Heating time cycle
• Parameters to configure for the Cooling PID are:
AL. = coo | cooL. Alarm selection as cooling
p.b.m : Proportional band multiplier
ou.d | ou.d.b.: Overlapping/Dead band
t.c.2: Cycle time for cooling output
Parameter p.b.m (that ranges from 1.00 to 5.00) determines the
proportional band of cooling basing on the formula:
Cooling proportional band = p.b. * p.b.m
This gives a proportional band for cooling which will be the
same as heating band if p.b.m = 1.00, or 5 times greater if p.b.m
= 5.00.
Integral time and derivative time are the same for both actions.
Parameter ou.d | ou.d.b. determines the overlapping
percentage between the two actions. For systems in which
the heating and cooling output must never be simultaneously
active a dead band (ou.d | ou.d.b. ≤ 0), can be configured, and
viceversa an overlapping (ou.d | ou.d.b. > 0):

10 Dead band function
The dead band function (enabled selecting F.b.M on par. 28 FNc
| Func.) creates a band within which the relays are both open
or closed.
In heating functioning (par. reG. selected on Hea | Heat), the
intervention threshold of the alarm relay will be SET1 - SET2
(with hyseresis selected on par. sYc) while the intervention
threshold of the command relay will be SET1 + SET2 (the
hysteresis is always sYc | Hys.c).
A band is created within which the relays are both open and
where the alarm relay operates above while the command relay
operates under the band limit.
In cooling functioning (par. reG. selected on co or | co oL) the
intervention thresholds of the two relays are reversed.

User manual - ATR121/141 - 2111 Serial communication
ATR121/141 is equipped with RS485, it can receive and
broadcast data via serial communication using MODBUS RTU
protocol. The device can be configured only as Slave. This
function enables the control of multiple devices connected
to a supervisory system. The RS485 line must be free of LT
termination resistances to avoid malfunctions.
Each controller will answer to a master query only if the query
contains same address as on parameter add | addr..
The allowed addresses range from 1 to 254, and there should
not be controllers with the same address on the same line.
Address 255 can be used by the master to communicate with all
the connected equipment (broadcast mode), while with 0 all
the devices receive the command, but no answer is expected.
ATR121/141 can introduce an answer delay (in milliseconds) to
master request. This delay has to be set on parameter. de.s |
dL.sr. (default 20ms).
At each parameter configuration, the device stores changed
values in the EEPROM memory (100000 writing cycles), while
setpoints are stored with a delay of 10 seconds after last
modification. NB: modifications made to words different from
those described in the following table can lead to instrument
malfunction.

Introduzione
Grazie per aver scelto un regolatore Pixsys.
Le versioni con display a tre e quattro digits permettono di
impiegare lo strumento in una vasta gamma di applicazioni,
ad esempio con sensori di temperatura, umidità, pressione,
livello o potenziometri lineari. Le soluzioni di uscita prevedono
sia il relè che la logica per SSR; è comunque configurabile
il funzionamento come solo visualizzatore per gli impianti
che non necessitano di uscite comando o di allarme. Con il
PID e l’Autotune è semplice adattare all’impianto l’algoritmo
di regolazione, mentre nel caso di funzionamento con
potenziometri lineari la funzione LATCH ON velocizza la
taratura della macchina.
Come sulla più recente strumentazione Pixsys sono disponibili
Memory-card per la configurazione in serie e per lo storico degli
impianti. Seguendo la tabella sottostante si può facilmente
identificare il modello desiderato.
1 Norme di sicurezza
Prima di utilizzare il dispositivo, leggere con attenzione le
istruzioni e le misure di sicurezza contenute in questo manuale.
Disconnettere l’alimentazione prima di qualsiasi intervento
sulle connessioni elettriche o settaggi hardware.
L’utilizzo/manutenzione è riservato a personale qualificato ed è
da intendersi esclusivamente nel rispetto dei dati tecnici e delle
condizioni ambientali dichiarate.
Non gettare le apparecchiature elettriche tra i rifiuti domestici.
Secondo la Direttiva Europea 2002/96/CE, le apparecchiature
elettriche esauste devono essere raccolte separatamente al fine
di essere reimpiegate o riciclate in modo eco-compatibile.

Benché questo regolatore sia stato progettato per
resistere ai più gravosi disturbi presenti in ambienti
industriali è buona norma seguire la seguenti
precauzioni:
• Distinguere la linea di alimentazioni da quelle di potenza.
• Evitare la vicinanza di gruppi di teleruttori, contattori elet-
tromagnetici, motori di grossa potenza e comunque usare gli
appositi filtri.
• Evitare la vicinanza di gruppi di potenza, in particolare se a
controllo di fase.

50 - ATR121/141 - Manuale d’uso9 Tuning
L’operazione di tuning consente di calcolare i parametri
PID al fine di ottenere una buona regolazione. Ciò significa
controllo stabile della temperatura/processo sul setpoint
senza fluttuazioni e risposta veloce alle deviazioni dal setpoint
causate da disturbi esterni.
L’operazione di tuning prevede il calcolo ed il settaggio dei
seguenti parametri:
• Banda proporzionale (inerzia del sistema in °C con
temperature).
• Tempo integrale (il tempo impiegato dal regolatore per
rimuovere segnalazioni di errore fisse, corrisponde all’inerzia
del sistema in tempo).
• Tempo derivativo (determina l’intensità della reazione del
regolatore alla variazione del valore misurato, normalmente
¼ del tempo integrale).
Durante il calcolo dell’autotune non è possibile cambiare il
setpoint.
9.1 Auto-tune
La procedura di Tuning per il calcolo dei parametri di regolazione
può essere manuale o automatica e viene selezionata da par.27
tun | tune.
9.2 Lancio del tuning manuale
La procedura manuale permette all’utente maggiore flessibilità
nel decidere quando aggiornare i parametri di regolazione
dell’argoritmo PID. Si attiva impostando Man nel par. 27 tun |
tune.
•Lancio del Tuning:
Premere FNC , il display visualizza t.of, premendo il display
visualizza alternativamente il valore del processo e tun | tune
fino al completamento della procedura (può durare qualche
minuto). Per annullare la procedura premere FNC e poi per
selezionare t.of.
Manuale d’uso - ATR121/141 - 519.3 Tuning automatico
Il Tuning automatico si attiva all’accensione dello strumento o
quando viene modificato il setpoint di un valore superiore al
35%. Si attiva impostando aut | auto nel par. 27 tun | tune.
Per annullare la procedura, lasciando invariati i valori PID,
premere FNC e poi per selezionare t.of.
9.4 Memory card (opzionale)
è possibile duplicare parametri e setpoint da un regolatore ad
un altro mediante l’uso della Memory Card.
Sono previste due modalità:
• Con regolatore connesso all’alimentazione:
Inserire la Memory Card con regolatore spento. All’accen-
sione il display visualizza m.no (solo se nella Memory sono
salvati valori corretti). Premendo il display visualizza
m-Ld. Confermando con FNC , il regolatore carica i nuovi valori
e si avvia. Premendo, invece, il display visualizza m-no e il
regolatore si avvia mantenendo invariati i valori.

52 - ATR121/141 - Manuale d’uso• Con regolatore non connesso all’alimentazione:
La memory card è dotata di batteria interna con autonomia
per circa 1000 utilizzi (batteria a bottone 2032, sostituibile).
Inserire la memory card e premere il tasto di programmazione.
Durante la scrittura dei parametri il led si accende rosso, al
termine della procedura si accende verde. è possibile ripetere
la procedura senza particolari attenzioni.
NB: non è possibile trasferire i parametri di uno strumento ad
uno con codice differente: il LED rimane acceso rosso.
Aggiornamento memory card.
Per salvare i parametri dal regolatore alla memory card,
inserirla a strumento acceso.
Entrare in configurazione e variare almeno un parametro.
Uscendo dalla configurazione il salvataggio dei parametri è
automatico e avviene sia all’interno dello strumento che nella
memory card.
9.5 Funzione Latch On
Per l’impiego con ingresso po1 (potenziometro ≤ 6K) e po2
(potenziometro ≤150K ) e con ingressi normalizzati (0..10Volt,
0/4..20mA), è possibile associare il valore di inizio scala (par. Lo.
n.) alla posizione di minimo del sensore e quello di fine scala
(par. Hi. n.) alla posizione di massimo del sensore, direttamente
sull’impianto.
è inoltre possibile fissare il punto in cui lo strumento visualizzerà
0 (mantenendo comunque il campo scala compreso tra Lo. n.
e Hi. n. ) tramite l’opzione di “zero virtuale” impostando u.0m
oppure u.0s nel par. 8 Lat | Latc.
Se si imposta u.0s, lo zero virtuale andrà riprogrammato dopo
ogni accensione dello strumento; con u.0m, lo zero virtuale
resterà fisso una volta tarato. Per utilizzare la funzione LATCH
ON configurare come desiderato il par. 8 Lat | Latc7.

La procedura di taratura parte uscendo dalla configurazione dopo aver
variato il parametro.
